CALEB S. GURNEY, OF PORTSMOUTH, NEW HAMPSHIRE.

UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 722,229, dated March10, 1903.

Application filed June 20, 1902. Serial No. 112,619. (No model.)

T (0 whom it may concern.-

Beit known that I, CALEB S. GURNEY, acitizen of the United States,residing at Portsmouth,in the county of Rockingham and State of NewHampshire, have invented a new and useful Umbrella, of which thefollowing is a specification.

This invention relates to umbrellas, and has for its object theconstruction of a means whereby the ribs and braces are coupled to thestandard and the braces coupled to the ribs in a simple, inexpensive,and durable manner, and that will not be liable to become broken ordisarranged.

The invention consists in certain novel features of the construction,ashereinafter shown and described, and specified in the claim.

In the drawings, illustrative of the invention, Figure 1 is a side viewof a portion of an umbrella frame embodying the improvements. Fig. 2 isan enlarged detail view of the lower member of the notch-piece. Fig. 3is an enlarged perspective view of the upper Fig. 4 is an enlargedsectional detail of the notch-piece and the runner. Fig. 5 is a planview of the lower member of the brace-coupling. Fig. 6 is an enlargedtransverse section on the line VI VI of Fig. 1. Fig. '7 is a perspectiveView, enlarged, of the coupling between the rib and the brace. Fig. 8 isa perspective View of a portion of one of the braces.

The device may be attached to any form of umbrella or parasol standardand will employ the ordinary ribs and braces. The standard isrepresented at 10, and embracing this standard at the point where theupper ends of the ribs are usually united is a notch member 11, with itslower end turned outward and formed with a series of spaced semisookets11 the sockets each being in the form of one-half of an ellipticalcavity with a contracted aperture 11, as shown.

Surrounding the standard 10 above the notch member 11 is another notchmember in the form of a sleeve 11', also provided with semi-ellipticalhalf-sockets 11 corresponding to and registering with the sockets 11, sothat when the two notch members are united upon the standard, as inFigs. 1 and 4, a series of elliptical sockets will be formed encirclingthe standard, as indicated in Fig. 2.

The ribs are indicated at 12, and each rib will be provided with anelliptical or oval head 12, adapted to engage the sockets 11 11, withthe portion of the rib next the head 12 preferably flattened andwidened, as at 12, and adapted to engage the contracted apertures 11, asshown in Figs. 4 and 5. By this means the ribs are supported movablybetween the notch members and are free to move vertically, but will beprevented from rotary movement by the elliptical heads 12, engaging thecorresponding elliptical sockets, together with the flattened portions,which coact with the elliptical heads to assist in holding the parts invertically-movable engagement. The notch members 11 11 will be firmlyattached to the standard 10 by any suitable meanssuch as pins 13 13. Theferrule 11, with its extended socket member 11, will be stamped orotherwise formed of a single piece, preferably of sheet metal, ofuniform thickness throughout, while the ferrule member ll will besimilarly formed, so that these parts of the structure will combinestrength and lightness, and consequent cheapness and durability. Theribs are thus supported in place independently and Without the use ofthe rivets, binding-wires, or other means usually employed for securingthe ribs in umbrellas.

Slidably disposed upon the standard 10 below the notch member 11 are twoother similar notch members 14 14, forming the runner, the member 14having laterally-extended semispherical sockets 14', similar to thesockets 11 on the notch member 11, except that the cavities therein aresemispherical instead of being semi-elliptical,and the runner member 14having the semispherical socket 14 and contracted aperture 14, similarto the notch member 11 and the aperture 11 as shown, except that theaperture is in the upper runner member instead of in the lower runnermember.

The braces are represented at 15 and each provided with a spherical head15, adapted to engage the spherical sockets between the two runnermembers 14 14, as shown, the shanks of the braces next the heads 15'engaging the apertures 14. By this means the braces are movablyconnected to the slidable runner and free to move vertically and alsofree to rotate in the sockets, but will be retained therein against endmovement.

The two parts of the runner 14 14. will be connected together, as byrivets 14:, but will be slidable upon the standard in the same mannerand for the same purpose as the ordinary slidable runner of the ordinaryumbrella.

The standard will be provided with the usual spring-supported clip 16,by which the runner 14 14 will be supported in its elevated position, asindicated in 1 and 4.

The outerends of the braces will be formed with T-heads 17, adapted toengage couplingplates 18, embracingthe ribs 12 intermediate of theirlengths at the usual points where the braces are connected to the ribsof umbrellas. Between the T-heads 1'7 and the ribs 12 the two parts ofthe couplings 18 are united by rivets 19, whereby the couplings arefirmly clamped to the ribs and at the same time prevented from spreadingand disengaging the T-heads. The braces 15 are thus supported verticallymovable around the T heads as centers, but will be prevented fromturning in or becoming detached from the couplings. This makes a verycomplete, simple, and durable coupling, readily applied and requiring noextra pins or rivets in the movable parts to become worn by friction orbroken by the strains to which they will be subjected.

The heads 17 will preferably be formed integral with the braces 15 andwill therefore not be weakened by any wear to which they will besubjected or weaken the ribs by the fact of their being attachedthereto. The

whole device is therefore a very complete, cheap, and durable structure,formed in few parts, easily repaired, and any part easily renewable.

' The invention can be applied to any umbrella, parasol, or sunshade andmay be modified as to sizes and dimensions without departing from thespirit of the invention or sacrificing any of its advantages.

It will be noted that the contracted portion 12 of the ribs 12 iswidened, as well as fiattened, to retain the area of the rib, so thatthe rib is not weakened at this point by the change of form. By thismeans also the contracted portions 11 may be reduced in width, andthereby correspondingly increase the gripping lengths of the ellipticalheads 12, and not only increase the strength of the notch, but alsoincrease the size of the elliptical head, and consequently the strengthof the joint.

Having thus described my invention, what I claim is In an umbrella, thecombination with a rib pivotally connected to a centrally-disposedstandard,of a clamp comprising a metal plate bent around the rib toenclasp the same and form a pair of arms spaced apart, said armsprovided with juxtaposed transverse perforations near their outer ends,a brace pivotally connected to said standard and having formed on itsouter end an integral T-head adapted to engage the perforations in theclamp, and a transverse rivet connecting the spaced arms of the clamp;whereby said arms will tightly engage the T-head to prevent itsaccidental escape but may be sprung apart to release the same whendesired.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

CALEB S. GURNEY.
